After each intake of medication, subjects completed a questionnaire using the following pain perception scores: 0, absent; 1, slightly perceptible; 2, mild; 3, severe; 4, intolerable pain. Statistical analysis was done according to a randomized block factorial design, and comparisons between mean values were done using the Tukey-Kramer test.
